Rislone Compression Repair with Ring Seal is a proprietary blend of petroleum additives developed for higher-mileage engines suffering from decreased or uneven compression that can be caused by normal engine wear and decreased sealing between the piston rings and cylinder walls. Compression Repair is formulated to fill scratches and grooves in cylinder walls to prevent blow-by gasses and compression from leaking past the rings and fouling the crankcase oil.
The additive also is made to free sticky rings to increase compression while reducing friction and wear. Compression Repair, which is compatible with any gasoline or diesel engine, does not contain any lead that could damage the inside of the engine or be burned and contaminate emissions components or the environment, and is made to work with all petroleum-based motor oils, including conventional, high-mileage and synthetic formulas.
